Definitions
- the invention relates to a medical device for treating sleep apnea, specifically a nasal continuous positive airway pressure (CPAP) device.
- CPAP involves the administration of air under pressure to a patient through a mask or any other suitable connection means.
- the positive air pressure from the CPAP device forces the upper respiratory tract open, prevents collapse of the pharynx and tongue over the air passage, and aids in increasing lung volume which improves the upper airway muscle dilation tone as air is exhaled.
- Sleep apnea syndrome is a sleep disorder characterized by recurrent, prolonged episodes of apnea (cessation of breathing) throughout the night causing excessive daytime sleepiness (hypersomnolence). While occasional periods of apnea during sleep are relatively harmless and occur in most adults, those suffering from sleep apnea syndrome experience episodes of breathing obstruction that last more than 10 seconds and which occur an average of 5 times per hour. Many sleep apnea patients experience apneic periods lasting more than 30 seconds, and have hundreds of such episodes throughout the night causing them to spend most of the night in airway obstruction.
- central sleep apnea a less common condition, in which the respiratory signals from the brain temporarily cease to stimulate respiratory effort
- mixed sleep apnea in which elements of both obstructive and central sleep apnea are present, usually as a central component followed by an obstructive component.
- obstructive sleep apnea is associated with factors that would easily cause obstruction of the upper respiratory tract.
- the presence of abnormal structures that impinge on airways such as large adenoids and tonsils in children, or bulky pharyngeal tissues in obese adults may reduce airway space, and patients with malformations of the chin, or with enlarged tongues may not be able to accommodate their tongues, causing them to fall back and block the airway.
- Nasopharyngeal tubes have been developed which are inserted into the upper airway to reach past the point of obstruction in order to maintain upper airway patency during sleep. While they do work, nasopharyngeal tubes are extremely uncomfortable, and most patients cannot tolerate them on a long-term basis.
- TRDs tongue restraining devices
- One newer TRD acts to pull the tongue away from the posterior wall of the pharynx, and appears to relieve sleep apnea to some degree in some patients.
- Investigators are unsure if patients will comply with long-term TRD therapy, and speculate that it may serve as a noninvasive method for temporary relief of apnea while patients are attempting weight reduction and other behavior modification changes.
- Tracheostomy for example, was one of the first approaches to surgically treat apnea.
- a tracheostomy tube bypasses the airway obstruction and allows a patient to breathe.
- Another surgical procedure called Uvulopalatopharyngoplasty or UPPP, removes redundant tissue in the patient's airway.
- the UPPP is a relatively new surgical approach which is currently being documented for its effectiveness.
- Maxillomandibular and hyoid advancement is a complicated multifaceted surgery that is presently being documented in medical journals. Although this particular type of surgery looks encouraging, its practice will be limited due to the cost and preclusion criteria for the surgery. The cost of surgery and the limited effectiveness of each of these procedures has thus limited its use.
- CPAP nasal continuous positive airway pressure
- Air pressure is measured in centimeters of water (cm H 2 O)
- CPAP typically delivers air to the patient at a pressure of 3.0 to 18 cm H 2 O.
- CPAP appears to act as a pneumatic splint on the pharyngeal area, that is, the positive air pressure from the CPAP device forces the upper respiratory tract open and prevents collapse of the pharynx and tongue over the air passages.
- CPAP aids in increasing lung volume which improves the upper airway muscle dilation tone as air is exhaled.
- CPAP therapy is successful in the sleep lab, the patient is sent home on CPAP therapy with regular follow-ups (either visits to the sleep lab or at-home monitoring) at 6-12 month intervals to assess patient compliance and improvement.
- the complications with nasal CPAP are relatively minor and include a reduction of sinus draining, drying of the nasal membrane (mucosa), and inflammation of the nasal mucosa (rhinitis).
- the available data regarding this treatment approach have led many physicians to conclude that CPAP is the best choice for therapy in patients with sleep apnea.
- Tranquility®Nasal CPAP System distributed by Healthdyne Corp., and is designed to eliminate some of the problems inherent in devices using CPAP valves.
- This device replaces the CPAP valve with a semiconductor pressure transducer and an electronic servo-control system that adjusts blower speed to maintain pressure. The device maintains pressure to calibrated setpoints so that the user knows what pressure would be delivered without having to adjust the machine while measuring the output pressure with an additional device.
- a device for treating sleep apnea by supplying pressurized air to the nasal passages of a user includes connection means for supplying pressurized air into the nasal passages of the user, generating means for generating pressurized air and for supplying the pressurized air to the connection means, and control means for controlling the pressure level supplied by the generating means.
- the control means comprises ramp means for selectively controlling the generating means to generate pressurized air at a pressure level which increases for a preset time to the prescribed pressure level, and switch means for overriding the ramp means and for controlling the generating means to immediately generate pressurized air at the prescribed pressure level.
- the means for overriding comprises a manually operated on-off switch operatively connected to the microprocessor.
- control means comprises a control unit having a digital microprocessor disposed therein.
- the generating means preferably comprises a blower and a variable speed motor connected to the blower and to the microprocessor.
- the ramp means preferably comprises a pressure transducer which generates a signal indicative of the pressure produced by the blower and which transmits the signal to the microprocessor.
- control means controls the motor so that the blower maintains a constant pressure whether the user inhales or exhales.
- a monitoring and recalibrating means which preferably comprises a valve which is located between the blower and the pressure transducer and which is controlled by the microprocessor to selectively connect the pressure transducer to the blower or to atmosphere.
- FIG. 1 illustrates a CPAP device constructed in accordance with a preferred embodiment of the invention
- FIG. 2 is a front view of the control unit of FIG. 1;
- FIG. 3 illustrates the pressure and time control dials of the control unit of FIG. 1;
- FIG. 4 is a schematic representation of the control device of FIG. 1;
- FIG. 5 is a graphical representation of the ramp function.
- the invention is a medical device for treating sleep apnea, specifically a nasal continuous positive airway pressure (CPAP) device.
- CPAP nasal continuous positive airway pressure
- the invention is an improvement over earlier CPAP devices because it produces low resistance to exhalation, generally responds faster to pressure changes, allows pressure to build up gradually, and allows the patient to adjust the mask at the prescribed pressure and subsequently return the device to a gradual pressure build-up mode.
- mask as used herein is understood to encompass any other suitable connection means for administration of pressurized air to the patient.
- a CPAP device comprises a control unit 1, a flexible tube 2, and a suitable device for injecting air into the patient's nasal passages, such as a mask 3 which seals over the patient's nose.
- the mask 3 preferably includes adjustable straps 3' for adjusting the tightness of the mask on the face of the patient 4.
- the control unit 1 includes a hose connection 11 which is provided for the hose 2, a power switch 13, and a switch 12, which is provided to test the seal of the mask in a manner discussed in greater detail below.
- This switch which will be referred to as a set-to-test switch for the sake of convenience, is illustrated as a simple binary switch.
- a pressure ramp time is adjustable by a suitable amount, e.g. 5 to 30 minutes, via dial 21, and the prescribed pressure of the device is likewise adjustable by a suitable amount, e.g. from 3 to 18 cm H 2 O, via dial 22.
- These rotary dials could, of course, be replaced by any suitable devices capable of performing the desired functions, such as sliding switches or a plurality of on-off switches which collectively perform the functions of the dials.
- the control unit 1 for the CPAP device preferably includes a variable speed electric motor 34 which drives a centrifugal blower 36 and which is controlled by a motor controller 32.
- the blower 36 provides pressurized air to the patient through the hose 2.
- the pressure is continuously monitored by a pressure transducer 38 which produces an electrical signal which is in turn amplified by the amplifier 40 and digitized by a suitable analog to digital convertor 42.
- This signal is received by a conventional microprocessor 30.
- the microprocessor is programmed to implement the ramp function as selected by the dials 21 and 22.
- the microprocessor also implements the set-to-test feature.
- the output from the microprocessor is a motor command 43 to the motor controller 32.
- the preferred microprocessor should be one which is capable of making the necessary and timely motor control corrections.
- a rapid response time allows the device to maintain a consistent therapeutic pressure in that it allows the CPAP device to promptly react to the patient's breathing pattern.
- the microprocessor 30 can control motor 34 to maintain the pressure constant whether the user is inhaling or exhaling, thus diminishing the uncomfortable sensation of increased pressure usually associated with exhalation.
- the microprocessor should be programmed to constantly monitor and recalibrate the pressure transducer.
- a valve 44 is provided in the air line connecting the blower 36 to the pressure transducer 38. This valve is periodically actuated by microprocessor 30 to connect transducer 38 to the atmosphere, at which point the pressure transducer is tested to determine whether or not it correctly reads zero, i.e. atmospheric pressure. For example, if, when valve 44 is actuated, the pressure transducer outputs a reading of 0.1 cm H 2 O, microprocessor 30 will subtract 0.1 cm H 2 O from future readings, thereby ensuring an accurate pressure reading. Following the calibration operation, the microprocessor 30 will deactivate valve 44 so that transducer 38 can resume its normal pressure monitoring operation.
- microprocessors can be easily programmed to perform the disclosed functions.
- One such microprocessor is manufactured by Intel Corp. under the part No. N-80C196KB-10.
- any system capable of increasing the output pressure at a selected rate up to a predetermined pressure level could be used.
- the gradual increase in pressure is shown graphically in FIG. 5 which shows that the pressure increases constantly, i.e., increases without significant decrease, during the time preset by operation by dial 21. Because the servo system is digital, all the variables are discrete or quantified. Therefore, the ramp is, so far as the control loop is concerned, a series of low amplitude steps each having a height dP in FIG. 5. In the actual implementation the steps are 1 second wide.
- the pressure step size is dependent on the ramp time and on the selected pressure. In the embodiment of FIG. 3, for example, the steepest ramp is a 5 minute ramp from 3 to 18 cm H 2 O, and the shallowest ramp is a 30 minute ramp from 3 to 4 cm H 2 O.
- the change in pressure dP per unit time for each case would be 0.05 cm H 2 O/sec. and 0.0005 cm H 2 O/sec., respectively.
- the pressure increases are illustrated as discrete steps in FIG. 5, in practice, the steps are not noticeable because they are so small.
- the output is a real physical variable and not a discrete value, any slight variations from the quantified level which consequently occur tend to smooth the steps.
- a very important feature of the present invention is the provision of the set-to-test switch 12, which enables the patient to test for leaks in the mask 3 and to adjust the mask to eliminate any leaks.
- a mask which appears to seal tightly at the minimum output pressure of the CPAP device may actually leak excessively at the prescribed pressure, thereby severely degrading the effectiveness of the device.
- the switch 12 is provided which, when pushed a first time, sends a signal to microprocessor 30 which causes the control unit to override the ramp function and to supply pressurized air at the prescribed pressure level previously. The patient can then adjust the mask to ensure that the mask will seal properly at the prescribed pressure.
- a second press of the switch deactivates the override feature, the pressure decreases, and the ramped increase of pressure is resumed.
- a ramped pressure increase in a CPAP device would be severely degraded in that the patient would not be able to assure a proper sealing of the mask until the pressure reaches its prescribed value.
- the primary purpose for employing a ramped pressure increase is to allow the patient to fall asleep before the pressure reaches its prescribed value, which purpose is destroyed if the patient must remain awake to ensure that the mask is properly sealed at the prescribed pressure.
- the illustrated embodiment utilizes a simple on-off switch as the set-to-test switch 21, it should be understood that any device capable of selectively making and braking an electrical current could be used as the set-to-test switch.
- a switch which, when pressed once, closes the circuit for a predetermined time interval and then reopens the circuit could be used in place of such an on-off switch.
- the "set-to-test" feature is a feature that could be implemented automatically without any switch, e.g. by a program control within the microprocessor.
- the microprocessor could be programmed to override the ramp at 5 seconds into the operation and to supply the prescribed selected pressure for a period of an additional 5 seconds. After this 5 second interruption, the pressure supplied by the unit would be reduced and the ramped pressure increase would resume.
- the device is set-up as shown in FIG. 1 with the patient placing the mask 3 over his nose.
- the prescribed pressure and ramp time interval are set using the dials 22 and 21.
- the patient then presses the set-to-test switch 12 and adjusts the mask to ensure an effective sealing at the prescribed pressure.
- the patient then presses the set-to-test switch a second time, in response to which the pressure supplied by control unit 1 drops to the ramp pressure.
- the device then begins to gradually increase the pressure over the selected time interval until the prescribed pressure is obtained. When the pressure reaches the prescribed level, the mask will be correctly adjusted to seal properly.
